Abstract
The utility model relates to an infrared induced switch for an electric lamp, comprising a door frame, an infrared inductor and a lighting lamp. The utility model is characterized in that the infrared inductor and the lighting lamp are arranged on the external side of the top end of the door frame, and the infrared inductor and the lighting lamp are connected into a current loop by an electrical wire in order to control the on-off state of the electric lamp. In the utility model with the structure, because of human approach, the infrared inductor is induced by the infrared radiation emitted by human's body temperature the current loop of the infrared inductor and the electric lamp is switched on. Accordingly, the electric lamp is turned on. Contrarily, because of human departure, the current loop is caused to be switched off, and the electric lamp is turned off. The utility model both makes people's life convenient and saves electric power.
Description
The utility model relates to the infrared sensing switch of electric light.
In busy life, many people often need return, when in the inlet chamber of desiring to open the door on the doorway, need in the faint environment of light, in a big string key, seek suitable person arduously, and taking after time finds key, must seek the position of the keyhole on the door again once more in dim, real is inconvenience.
The purpose of this utility model be to provide a kind of can be because of people's the device of walking close to open automatically electric light.
The utility model is to realize like this, the induction door device of automatic open and close electric light, comprise a doorframe, an infrared inductor and an illuminating lamp, infrared inductor and illuminating lamp are located at the outside, doorframe top, and this infrared inductor connects into current loop with electric wire and illuminating lamp.
Have described structure the utility model is arranged, owing to people's conducting near making infrared inductor be subjected to infrared induction that people's body temperature sends its with the current loop of electric light, thereby electric light is opened, leaving away owing to the people on the contrary, disconnect this current loop and cause, electric light is closed.Both be convenient for people to life, saved electricity charge expenditure again.
The following drawings and embodiment will be described further architectural feature of the present utility model:
Fig. 1 is the stereogram of the utility model embodiment.
Fig. 2 is the plan view of the utility model embodiment.
Embodiment:
As shown in Figure 1, 2, the utility model comprises a doorframe 1, an infrared inductor 2 and an illuminating lamp 3, and infrared inductor 2 and illuminating lamp 3 are located at the outside, doorframe 1 top, and this infrared inductor 2 connects into current loop with electric wire and illuminating lamp 3, with the keying of control electric light 3.
The utility model with described structure, owing to people's conducting near making infrared inductor 2 be subjected to infrared induction that people's body temperature sends its with the current loop of electric light 3, thereby electric light 3 is opened, leaving away owing to the people on the contrary, disconnect this current loop and cause, electric light 3 is closed.Both be convenient for people to life, it only is people by outdoors that outside line inductor 2 is sensed, and causes the unnecessary light on and off of illuminating lamp 3, and the size of visuable door external space scope is selected suitable infrared inductor 2.
